Nas versões anteriores do Python, você poderia utilizar threads ou <a href="http://www.gevent.org/" class="external-link" target="_blank">Gevent</a>. Mas o código é um pouco mais complexo de entender, debugar, e pensar sobre.

Nas versões anteriores do NodeJS / Navegador JavaScript, você poderia utilizar "callbacks". O que leva ao  <a href="http://callbackhell.com/" class="external-link" target="_blank">inferno do callback</a>.

## テスト駆動開発のコース

このセクションの内容を補完するために脱初心者用コースを受けたい場合は、**TestDriven.io**による、<a href="https://testdriven.io/courses/tdd-fastapi/" class="external-link" target="_blank">Test-Driven Development with FastAPI and Docker</a>を確認するのがよいかもしれません。

# Form Models

You can use **Pydantic models** to declare **form fields** in FastAPI.

/// info

To use forms, first install <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then install it, for example:

```console
$ pip install python-multipart
```

Hiding the documentation just makes it more difficult to understand how to interact with your API, and could make it more difficult for you to debug it in production. It could be considered simply a form of <a href="https://en.wikipedia.org/wiki/Security_through_obscurity" class="external-link" target="_blank">Security through obscurity</a>.

If you want to secure your API, there are several better things you can do, for example:
